Assistir Wind Vane online dublado e legendado

Documentário

Two cameras mounted on tripods with wind vane attachments were positioned about 50 feet apart along an axis of 45 degrees to the direction of the wind. Both cameras were free to pan through 360 degrees in the horizontal plane. There are three continuous 100 foot takes for each screen. The movements of the two cameras, which were filming simultaneously, were controlled by the wind strength and direction.
